Write the coefficient of $x^{2}$ in the following polynomial: $\sqrt{3} x^{2}+11$.

Write the following cube in expanded form:
$(2a - 5b)^3$

If $p(x) = x + 3,$ then $p(x) + p(-x)$ is equal to

Which of the following expressions are polynomials in one variable and which are not? State the reason for your answer. If the given expression is a polynomial,state whether it is a polynomial in one variable or not: $\pi x^{2}-\sqrt{3} x+11$

Find $p(1)$,$p(2)$,and $p(4)$ for the polynomial $p(x) = x^3 + 9x^2 + 23x + 15$.

Dividing $x^{3} + 125$ by $(x - 5)$,the remainder is $\ldots \ldots \ldots .$
